HELIUM KREW

I am searching for a long lost mix tape by a group called the HELIUM KREW out of what I think might be Philadelphia PA. It was released in the mid to late 90's. It had a good deal of impressive scratching. It also had the classic "enter the dragon" TOV release from around the time... the mix tape was a classic and a friend of mine and I wore it out... and then it disappeared...
Anyone ever heard of this krew? Heard the tape? Know of where a copy could be located? I seem to remember the MC occasionally called out to a group called the "whistle posse"... if that helps track down the tape...
